The drive assembly is connected to the partition plate, and the material blocking component is connected to the drive assembly. The drive assembly drives the material blocking component to move so that the material blocking component blocks at least a portion of the second material conveying hole or is offset from the second material conveying hole (202).

Detailed Implementation

[0029] The specific embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and are not intended to limit the scope of the invention.

[0030] like Figures 1 to 5As shown, a material conveying device according to an embodiment of the present invention includes a conveying cylinder 1, a partition plate 2, and a baffle mechanism 3. The conveying cylinder 1 is rotatable about its axis. The partition plate 2 is disposed inside the conveying cylinder 1, and the thickness direction of the partition plate 2 extends along the axial direction of the conveying cylinder 1. The peripheral wall surface of the partition plate 2 is connected to the inner wall surface of the conveying cylinder 1. The partition plate 2 has a first conveying hole 201 and a second conveying hole 202 that penetrates along its thickness direction. The baffle mechanism 3 includes a driving assembly 31 and a baffle member 32. The driving assembly 31 is connected to the partition plate 2, and the baffle member 32 is connected to the driving assembly 31. The driving assembly 31 drives the baffle member 32 to move so that the baffle member 32 blocks at least a portion of the second conveying hole 202 or is offset from the second conveying hole 202.

[0031] The material conveying device of the present invention has a conveying cylinder 1 that rotates around its axis to achieve mixed conveying of materials. A partition plate 2 is provided inside the conveying cylinder 1. A first conveying hole 201 and a second conveying hole 202 are provided on the partition plate 2. The first conveying hole 201 and the second conveying hole 202 form a channel for material conveying. In practical applications, the material conveying device can drive a baffle 32 to block the second conveying hole 202 through a drive component 31, so that the channel is partially closed. The baffle 32 will block part of the material output, thereby prolonging the time that the material stays in the material conveying device, so that the material has a relatively good mixing effect.

[0032] When the material conveying device needs to accelerate the output of material, the drive assembly 31 drives the stop member 32 to move, so that the stop member 32 no longer blocks the second conveying hole 202. At this time, the above-mentioned channel is fully open, thereby enabling the material to be output quickly. In addition, the drive assembly 31 provides driving force for driving the stop member 32 to move. Specifically, it can adopt the structure of the following embodiment, or it can adopt a power component that can drive the stop member 32 to move in the prior art. There is no limitation on this.

[0033] For example, the second feed hole 202 and the first feed hole 201 may be interconnected. In this embodiment, when the drive assembly 31 drives the stop member 32 to move, and the stop member 32 does not block the second feed hole 202, the first feed hole 201 and the second feed hole 202 are in a state of interconnection, so that the material can pass through more easily and the material conveying is more smooth.

[0034] In another embodiment, the first feed hole 201 and the second feed hole 202 may be disconnected. In this embodiment, when the baffle 32 does not block the second feed hole 202, the material will pass through the first feed hole 201 and the second feed hole 202 respectively. Since the first feed hole 201 and the second feed hole 202 are not connected, some material will be blocked, but this does not affect the continuous conveying, mixing and residence time adjustment of the material.

[0035] In summary, to ensure smoother material conveying, preferably, the first conveying hole 201 and the second conveying hole 202 in this embodiment are interconnected.

[0036] like Figure 2 and Figure 3 As shown, the first feeding hole 201 is located at the center of the partition plate 2, and there are multiple second feeding holes 202 arranged at intervals around the center of the partition plate 2. There are multiple baffle mechanisms 3, and each second feeding hole 202 is provided with a corresponding baffle mechanism 3. The arrangement of multiple second feeding holes 202 ensures that the above-mentioned channel has sufficient flow space, and the material can be output quickly when the channel is fully open. The number of baffle mechanisms 3 is adapted to the number of second feeding holes 202, thereby controlling the degree of shielding of each baffle 32 on the corresponding second feeding hole 202, so that the shielded area of ​​each second feeding hole 202 is the same or different, and the residence time of the material in the conveying cylinder 1 can be flexibly controlled, thereby enabling the material to have a better mixing effect.

[0037] like Figure 2 As shown, the baffle 32 is plate-shaped, with one side attached to the partition plate 2 and the other side directly or indirectly connected to the drive assembly 31. That is, the connection between the baffle 32 and the drive assembly 31 can be either a direct connection between the surface of the baffle 32 and the drive assembly 31, or an indirect connection via an auxiliary component. Furthermore, the area of ​​the baffle 32 is greater than or equal to the area of ​​the second feed hole 202. Therefore, depending on actual needs, the baffle 32 can completely cover the second feed hole 202, which helps to further extend the residence time of the material in the conveying cylinder 1.

[0038] It should be noted that setting the area of ​​the baffle 32 to be greater than or equal to the area of ​​the second conveying orifice 202 is to ensure that the baffle 32 can block at least a portion of the second conveying orifice 202, thereby extending the time the material spends in the material conveying device. If the area of ​​the baffle 32 is smaller than the area of ​​the second conveying orifice 202, the blocking effect of the baffle 32 on the second conveying orifice 202 will be greatly reduced, which is not conducive to extending the residence time of the material in the conveying device. Preferably, in this embodiment, the area of ​​the baffle 32 is set to be larger than the area of ​​the second conveying orifice 202.

[0039] like Figure 2 As shown, the material blocking mechanism 3 also includes a guide rail 33 and a sliding member 34. The guide rail 33 is connected to the partition plate 2, and the end of the sliding member 34 is slidably connected to the guide rail 33. The sliding member 34 connects the material blocking member 32 and the drive assembly 31. The guide rail 33 ensures that the material blocking member 32 moves smoothly along a predetermined straight direction, ensuring that the material blocking member 32 can smoothly block the second material feeding hole 202.

[0040] like Figure 4 As shown, the drive assembly 31 includes a motor 311, a lead screw 312, and a nut 313. The motor 311 is connected to the partition plate 2, the lead screw 312 is connected to the power output end of the motor 311, and the nut 313 is connected to the lead screw 312 and to the sliding member 34. The guide rail 33 is parallel to the lead screw 312. When it is necessary to extend the residence time of the material in the conveying cylinder 1, the motor 311 drives the lead screw 312 to rotate, thereby causing the nut 313 to move along the length of the lead screw 312, so as to drive the sliding member 34 to move in a straight direction. The linear motion drives the stop 32 to block at least part of the second feed hole 202. The advantage of this type of drive assembly 31 is that the pitch of the lead screw 312 is a fixed value. For each rotation of the nut 313, the distance it moves along the axial direction of the lead screw 312 is equal to the pitch of the lead screw 312. Therefore, by controlling the rotation angle of the motor 311, the moving distance of the nut 313 can be precisely controlled to achieve precise positioning. Based on this, the moving distance of the stop 32 can be precisely controlled, which is beneficial to controlling the residence time of the material in the conveying cylinder 1.

[0041] It should be noted that the power supply and control of motor 311 can be achieved through slip rings so that the motor can rotate with conveyor cylinder 1. The specific setting method depends on the actual application, and this application will not elaborate on it further.

[0042] like Figure 2 As shown, the motor 311 is located on the side of the second feeding hole 202 away from the first feeding hole 201, and the lead screw 312 extends radially along the conveying cylinder 1. The motor 311 is reasonably positioned, making full use of the space between the inner and outer edges of the partition plate 2. The material conveying device has a compact structure.

[0043] Furthermore, such as Figure 2 As shown, there are two guide rails 33, which are respectively arranged on opposite sides of the second feed hole 202; the sliding member 34 includes a connecting rod 341 and a reinforcing plate 342. There are at least two connecting rods 341, and the two ends of the connecting rods 341 along their length direction are slidably connected to the two guide rails 33 respectively. Adjacent connecting rods 341 are connected by the reinforcing plate 342; the stop member 32 is connected to the side of the connecting rod 341 near the second feed hole 202, and the nut 313 is connected to the middle of the connecting rod 341. Specifically, there are at least two connecting rods 341. The connecting rods 341 can stably connect to the stop member 32 and make the stop member 32 move smoothly. Adjacent connecting rods 341 are connected by the reinforcing plate 342. Therefore, the sliding member 34 has the advantage of stable and reliable structure.

[0044] Furthermore, such as Figure 1 , Figure 2 and Figure 5As shown, the material conveying device also includes multiple conveying plates 4, which are arranged at intervals around the first material conveying hole 201. In the axial direction of the conveying cylinder 1, one end of each conveying plate 4 is connected to the partition plate 2, and the other end extends a predetermined distance along the axial direction of the conveying cylinder 1. In the radial direction of the conveying cylinder 1, one end of each conveying plate 4 is connected to the inner wall surface of the conveying cylinder 1, and the other end is bent to form a guide groove 401. The guide groove 401 communicates with the first material conveying hole 201, and the guide groove 401 is inclined from the center of the conveying cylinder 1 towards the inner wall surface of the conveying cylinder 1 in a direction away from the partition plate 2 in the radial direction of the conveying cylinder 1. Along the circumferential direction of the conveying cylinder 1, each conveying plate 4 is bent to the same side to form the guide groove 401, while the opposite side is a smooth surface. Specifically, as shown... Figure 1 As shown, the left side of the conveyor cylinder 1 is the feed side, and the right side is the discharge side. Based on the arrangement of the conveyor plate 4, when the conveyor cylinder 1 rotates clockwise (e.g., ...), the feed side is on the left and the discharge side is on the right. Figure 2 As shown visually (rotation from right to left), the material guide trough 401 will convey the material towards the feeding side, increasing the material's residence time and simultaneously mixing it in multiple directions, including reciprocating forced mixing along the axial direction of the conveyor cylinder 1 and free mixing in the radial direction by gravity, making the mixing more uniform and the mixing efficiency higher. When the conveyor cylinder 1 reverses, the smooth surface of the conveyor plate 4 will convey the material towards the discharge side, which can discharge all the remaining material out of the cylinder, achieving self-cleaning of the cylinder, reducing the time and difficulty of cleaning and switching production, reducing the cost of use, and increasing work efficiency.

[0045] like Figure 1 and Figure 2 As shown, the baffle mechanism 3 and the conveying plate 4 are respectively set on both sides of the partition plate 2 in the axial direction of the conveying cylinder 1. At this time, the space on the opposite sides of the partition plate 2 is fully utilized, which facilitates the installation of the baffle mechanism 3 and the conveying plate 4.

[0046] like Figure 1 As shown, there are at least two partition plates 2, and each partition plate 2 is equipped with a baffle mechanism 3 and a conveying plate 4. This can effectively extend the residence time of the material in the conveying cylinder 1, so that the material has a better mixing effect.

[0047] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present invention, and these improvements and substitutions should also be considered within the scope of protection of the present invention.
